摘　　要：以地方标准中的晚稻寒露风防御技术规程为灾害指标,利用贵港市3个国家级地面气象观测站(贵港、桂平、平南)1961年—2020年逐日平均气温、降雨量和贵港市农业农村局播种以及晚稻抽穗扬花期等晚稻生产资料,找出贵港市晚稻抽穗扬花和灌浆乳熟期的寒露风天气发生的基本特征。结果表明:平南受轻、中、重3种等级寒露风影响相对较小,桂平居中;湿冷型寒露风发生日数为贵港最多,其次是平南,贵港市3站点的晚稻敏感期寒露风加强发生的周期基本相似,其日数序列存在相同的时间特征尺度:10年、30年。其中30年的振荡周期相对偏强,8年的振荡周期偏弱。Taking the late rice cold dew and wind prevention technical regulations in local standards as disaster indicators,the daily average temperature and rainfall of three national surface meteorological observation stations(Guigang,Guiping and Pingnan)in Guigang City from 1961 to 2020,and the production data of late rice such as sowing and late rice heading and flowering period of the Agriculture and Rural Bureau of Guigang City were used.To find out the basic characteristics of cold dew and wind weather in late rice heading and flowering and filling and milk ripening in Guigang City.The results show that the south of Pingping is less af‐fected by light,medium and heavy cold dew wind,while Guiping is in the middle.Guigang had the largest number of cold dew days,followed by Pingnan.The cycles of cold dew wind strengthening in the sensitive period of late rice at the three stations in Guigang were basically similar,and the series of days had the same time characteristic scale:10 years and 30 years.The 30-year oscillation pe‐riod is relatively strong and the 8-year oscillation period is relatively weak.
